Human Impacts

Christopher Costello

I am a professor of Environmental and Resource Economics at the Bren School of Environmental Science & Management, UC Santa Barbara. My research concerns natural resource management and property rights under uncertainty, with a particular emphasis on information, its value, and its effect on management decisions.

Bruce Kendall

Bruce Kendall is a quantitative ecologist whose research in population dynamics involves modeling and analysis of abundance (the number of individuals in a plant or animal population) and demographic (birth and death rate) data. He applies the science of population ecology both to the conservation of rare species and the management of harvested populations.

My research sits at the interface of ecosystem and microbial ecology. I am interested in the role of soil microbes in controlling ecosystem scale processes. I am particularly interested in the linkages between plant and soil processes, and how changes in microbial community structure affects ecosystem-scale dynamics. My work is now focusing on three ecosystems: the Arctic tundra in Alaska, the taiga forest of Alaska, and the California annual grassland-oak savanna.

Research interests lie in the general field of aqueous geochemistry and center on: 1) the transport of water and dissolved material in groundwater, surface waters, and the coastal ocean; 2) how flow patterns affect water quality; 3) gas exchange across the air-water interface; 4) climate change during the last 30,000 years. These questions are examined using experiments conducted by introducing chemical tracers into the water bodies, plus analysis of flow patterns, residence times, and mixing rates inferred from the distribution of natural and anthropogenic tracers.

Microbial Oceanography is an interdisciplinary blend of marine microbiology and ocean biogeochemistry. Specifically, our research has focused on the role marine microbes play in the cycling of elements through oceanic dissolved organic matter (DOM) and the biogeochemical significance of DOM in the marine C cycle. Despite significant progress the oceanographic community still lacks a mechanistic understanding of the microbial processes that shape DOM dynamics. My groups’ research goals are to continue to break apart the “black boxes” of substrates and organisms.

Michael Singer

My research focuses on hydrology and sediment transport processes, particularly in large river basins, in order to understand how the hydrologic cycle is modified by climatic changes and humans, and how such alterations affect sediment mobilization from terrestrial environments, sequestration and biogeochemical transformation within floodplains and deltas, and ultimately delivery to oceans.

Laura Hess

My research focuses on remote sensing, field, and modeling studies in order to quantify key drivers of land cover and land use change on the lower Amazon floodplain.
